1.The antenna must be kept as straight as possible. Otherwise it will reduce the effective range.
2.Large model aircraft may of some metal part interfering signal; in this case the antennas should be placed at both sides of the model. Then the best RF signal condition is obtained at any flying attitude.
3.The antennas must be kept away from conductive materials, such as metal and carbon by at least a half inch. The coaxial part of the antennas does not need to follow these guidelines, but do not bend it in a small radius.
4.Keep the antennas away from the motor, ESC, and other noise sources as much as possible.
